Building these DIY kits happens on your own risk. We can't do support or give a guarantee for correct function, because that depends on your own skills. Be
responsible and check the building instructions before you buy. Thank you!

All AI Synthesis DIY kits have a very educational approach. They are easy to build, sound good and are suitable for DIY beginners. If you are looking for
something to start with: this is it!

AI Synthesis AI001 - Multiple

The Multiple module can be used as either a 2×4 passive multiple, or a 1×7. The first set of four are linked together, and if nothing is plugged into the 5th jack, then that signal continues to
the 6th, 7th, and 8th as well. If a cable is plugged into the 5th jack, then those signals are distributed to the 6th, 7th, and 8th jacks and it functions as a 2×4 multiple. This kit is compiled by Exploding Shed, in case you have problems please contact us and not AI Synthesis.

Width: 2HP, skiff friendly

Current draw: none - it's passive

This is a Do-It-Yourself kit, not an assembled module. Building instructions can be found here.

AI Synthesis AI003 - Looping ADSR

The AI003 DIY Kit is a looping ADSR Envelope Generator. It can be manually triggered via Momentary Push Button, Gated via the Gate Signal, Triggered or re-triggered by a Trigger input, or set
into a loop mode via a toggle switch. An LED shows the status of the output. Here is a YouTube video
about it.

In Gate or Trigger mode, the envelope can be used as a traditional ADSR envelope generator. In loop mode, the output sends a variable exponential waveshape between Ramp, Triangle, and Sawtooth
LFO with control over the attack and decay of the LFO shape. The modes are dependent on whether or not the gate jack is inserted, and for triggers, the Sustain level - see the chart below. We
will be releasing a more traditional ADSR with "normal" gating functions shortly (but with twice the part count and no AD loop). Check picture (table) for the mode overview.

Minimum Gate/Trigger Signal: 2V

Attack Time: 20ms - 14 seconds

Decay Time: 10ms - 20 seconds

Release Time: 100ms - 7 seconds

Max Voltage (when run off +/- 12V): 7.5V

Width: 8HP, skiff friendly

Current draw 15mA +12V / 14mA -12V

This is a Do-It-Yourself kit, not an assembled module. Building instructions can be found here.

AI Synthesis AI004 - OTA VCF (MS 20 Filter)

A Loving Tribute to the MS 20 Filter! This OTA Voltage Controlled Filter uses the same filter structure as the venerable Korg MS 20 Filter. The filter is switchable between Lowpass and Hi Pass
modes, and features an updated diode gain stage in the resonance section. The VCF will overdrive and distort in both the HP and LP modes, and the resonance can self-oscillation. As with the MS 20
Filter, the Low Pass slope is 12dB/octave and the High Pass slope is 6dB/octave. The CV input is an attenuverter, allowing for dynamic control-voltage of the cutoff. Here is a YouTube video about it.

All jacks, knobs, and other components are soldered directly to the PCB. There is no wiring, making this kit ideal for those who have built a simple module before, and are looking for a high
quality, legendary filter in an easy to build package.

Width: 8HP, Depth: 60mm

Current draw 15mA +12V / 15mA -12V

DIY level: easy. Very good for beginners like all AI Synthesis DIY kits.

AI Synthesis AI006 - Stomp Box Adapter

The AI006 Eurorack Stomp box Adapter is an updated take on a classic utility circuit that converts the higher signal levels of a modular system to be converted to the lower level signals that
most stomp boxes are designed for. The AI006 stomp box adapter solves two problems. From the Synth input to the "FX"out, the signal is reduced by a factor of 20 to match the signal levels
expected by most stomp boxes. From the "FX" input to the Output, the signal is increased by a factor of 20. Passive attenuators are present on both the send and return in case the input or output
levels are too great. Here is a YouTube video about it. This kit is compiled by Exploding Shed, in case you have problems please contact us and not AI Synthesis.

Width: 2HP

Current draw 15mA +12V / 15mA -12V

DIY level: easy. Very good for beginners like all AI Synthesis DIY kits.

AI Synthesis AI008 - Matrix Mixer

The AI008 Matrix Mixer is an active, Four In, Three Out matrix Mixer with a summed output. The AI008 can be used to route any of the inputs to any of the outputs. This allows for the creation of
feedback patches and other interesting routing, in addition to powerful "regular" signal routing. Common uses include mixing effects outputs into their inputs in order to create drones (or just
good old fashioned feedback), mixing oscillators into their own PWM or FM inputs, modulating voltage controlled LFOs and other modulators into themselves, and other feedback patches. The AI008
Matrix mixes is a powerful way to expand any system! Here are 2 YouTube video about it: ONE,
TWO. This kit is compiled by Exploding Shed, in case you
have problems please contact us and not AI Synthesis.

Width: 10HP, Depth: 35mm

Current draw 17mA +12V / 17mA -12V

AI Synthesis AI010 - Switching Attennuator

The AI010 Eurorack Attenuator is a 2hp dual passive attenuator with switched jacks that allow the attenuator to also work as a multuple. The top-most input is normalled to the second attenuator
knob and the third attenuator input. Control voltage is a wonderful way to add expression to a modular patch, and controlling that control voltage is crucial to being able to dial in that
expression. A passive eurorack attenuator is a simple un-powered circuit using only resistive elements (usually a potentiometer) to reduce voltage. Rotating the potentiometer will change the
output from 0V to 100% of the input without distorting the shape of the incoming voltage. These are simple and primitive, but effective and important methods of controlling voltage, be it the
input to a Filter, or the Linear Frequency Modulation input on an Oscillator.
